End score (consolidation, power etc.)

Our virtualization project has come to an end a while ago but I would like to share the end score and some of the savings achieved with this project:

Our current VI consists of:

• Six cluster hosts (DL585 G2, 48GB memory per host)
  • 120 Virtual Servers (consolidation 20:1)
• Two VDI hosts (DL585 G1, 32GB memory per host)
  • 50 desktops (currently, there’s room for more)
• One dedicated ESX3 host for SAP testing and development purposes
• One dedicated ESX3 host for Lotus Notes / Domino testing and development purposes
  • The above two servers have lower continuity requirements and are therefore stand-alone machines (not part of the cluster)
• 1 Virtual Center Management Server

Real estate saved (focusing on servers only, not the VDI):

• Total rack units used for VI: 30
• Total racks used for VI: 2
• Total rack units saved: 240
• Total racks saved: 8
• Total sq. meters saved: 50 (we would have had to move into a datacenter suite twice as large to accomodate for growth)
• Total real estate cost (OTC) saved: € 30.000 (approx.)
• Total real estate cost (MRC) saved:  € 6.000 (approx.)
  • OTC: One Time Charge
  • MRC: Monthly Recurring Charge

Power savings:

• Extrapolated extra power requirement: 10 - 15 KiloWatts
• Estimated monthly power savings: € 1500 - 2500

There are also additional benefits like the massive increase in continuity, the time saved on provisioning new servers and the transparency in costs.
